Mitogen-activated protein kinases (MAPKs) signal is one of the important ways in eukaryotic cell,which adjusts and controls the structure and function of the cell. MAPKs in eukaryotes include p38, ERK, JNK and ERK5, etc. With the deepening research,we found that the activation of p38, ERK, JNK signal pathways were closely related with osteoarthritis (OA) cartilage injury. MAPKs are the key signaling systems involved in the production of matrix metalloproteinases and the regulation of cartilage cell proliferation, apoptosis and differentiation. Expecially the matrix metalloproteinases can accelerate the degradation of articular cartilage. So it has been the new spot in pathogenesis of osteoarthritis study.

Objectives: To investigate the protective effects and underlying mechanisms of extract on motor dysfunction in mouse model of Parkinson's disease (PD).
Methods: Eighty C57BL/6 male mice were randomly divided into five groups: control group, PD model group, levodopa treatment group (positive control group), low-dose GP treatment group (LD-GP group), and high-dose GP treatment group (HD-GP group), with 16 mice per group. The PD model was induced by injection of 6-hydroxydopamine into the substantia nigra pars reticulata in mice of last 5 groups.

Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by immune dysregulation and excessive cytokine production. This study aimed to explore the potential of Camellia sinensis L. water extract (CSE) as a treatment for AD by the impact of CSE on inflammatory responses in keratinocytes, particularly concerning the production of inflammatory cytokines and the modulation of signaling pathways relevant to AD pathogenesis.

Objective: To investigate the effect of basic fibroblast growth factor (bFGF) on hypoxia-inducible factor (HIF)-1α expression (Exp) and HIF-1 transcription in breast cancer (BC) cells.
Methods: Human BC cell line T47D was utilized as the research object. Western blot and dual-luciferase system were utilized to detect HIF-1α Exp induced by bFGF in BC cells under hypoxia and normal oxygen conditions, as well as the Exp of phosphorylated ERK1/2, Akt, and p38 proteins, HIF-1α Exp induced by bFGF under kinase inhibitors' action, and HIF-1 transcription, thereby summarizing the impact of bFGF on BC cells and its association with PI-3 K Akt signaling pathway (SPW).

Cell-containing biomaterial is a promising material for treating nonunion or critical bone defect. Human adipose-derived stem cells (hADSCs) are suitable for bone repair due to their abundance in the abdomen, thighs, and buttocks. However, the low osteogenic capacities of hADSCs hinder their extended development for bone regeneration application.
